Frecuencia de los ciclones tropicales que afectaron a Costa Rica durante el siglo XX
(2003)Se estudia la frecuencia de ciclones tropicales que pasaron por el Mar Caribe y que afectaron indirectamente a Costa Rica durante el siglo XX. De un total de 125 ciclones, ninguno de ellos pasó sobre Costa Rica, siendo la ... -
Frequency and synchronisation features of a highly overlapped duet changes according to the context
(2019)Territorial defence and maintaining contact are two hypotheses of duet functions. Nevertheless, the acoustic characteristics of duets in these contexts have been poorly quantified. This work aimed to compare the spectrotemporal ... -
Fresh biochar application provokes a reduction of nitrate which is unexplained by conventional mechanisms
(2021)Soil-applied biochar has been reported to possess the potential to mitigate nitrate leaching and thus, exert beneficial effects beyond carbon sequestration. The main objective of the present study is to confirm if a pine ... -
Freshwater crabs as predators and prey: the case of Ptychophallus uncinatus Campos & Lemaitre, 1999 (Brachyura, Pseudothelphusidae) from Costa Rica, Central America
(2019)Primary freshwater crabs are an important component of the food web in aquatic ecosystems, but our knowledge about the role of these decapods as predators and as prey is far from complete. Here we report observations of ... -
Freshwater Decapod Diversity and Conservation in Central America and the Caribbean
(2016)This chapter provides an overview of the species diversity and conservation status of the freshwater decapods in Central America and the Caribbean islands that date back to the late 1800s in both areas. The majority of the ... -
From Cobalt Laterites to Baseball, Goldschmidt 2018 in Boston
(2018-09-28)Este blog describe las actividades académicas de los integrantes del Geomicro Group de la University of Manchester, Reino Unido, liderado por el Prof. Jonathan Lloyd. Esta publicación en particular, fue escrita por Agustín ... -
From dirt to industrial applications: Pseudomonas putida as a Synthetic Biology chassis for hosting harsh biochemical reactions
(2016-10)The soil bacterium Pseudomonas putida is endowed with a central carbon metabolic network capable of fulfilling high demands of reducing power. This situation arises from a unique metabolic architecture that encompasses the ... -
From geometric quantization to Moyal quantization
(1995-06)We show how the Moyal product of phase-space functions, and the Weyl correspondence between symbols and operator kernels, may be obtained directly using the procedures of geometric quantization, applied to the symplectic ... -
From Ideality to Simplicity: A Robust and Affordable Hydrogen Reference Electrode
(2020-02-01)In electrochemistry, the concept of a reference electrode is fundamental. Introductory courses might mention the standard hydrogen electrode (SHE), its working principle, and its theoretical design; however, chances are ... -
¿Funcionan realmente los microorganismos de montaña (MM) como estrategia de biofertilización? Un enfoque de ingeniería de biosistemas
(2017-06-29)El uso de microorganismos en aplicaciones ingenieriles, en particular desde un contexto de ingeniería de biosistemas tropicales, es útil para comprender el efecto de variables que determinan la dinámica microbiológica ... -
Function of the upper tangle in webs of young Leucauge argyra (Araneae: Tetragnathidae)
(2011)Ontogenetic changes in web structure occur in many spiders of different families, but the functional adaptation of differences in web structure is unknown for most species. We describe the ontogenetic changes in web structure ... -
Functional aspects of genital differences in Leucauge argyra and L. mariana (Araneae: Tetragnathidae)
(2013)Morphological studies have documented the tendency for male genitalia to diverge rapidly compared to other body parts in many animal groups, including spiders. But documentation of how differences in genital structures of ... -
Functional changes in web design along the ontogeny of two orb-weavers
(2017-08-01)Orb webs evolved primarily to capture prey, though they also have other functions. Recently, it has been argued that the orb web does not work as a functional unit, but instead some sections or components have presumably ... -
Una fundamentación instrumental de la Aritmética
(1990)Desde el punto de vista de la génesis histórica y psicológica del conocimiento humano, poca duda cabe que los números naturales van siendo elaborados como referente social en el proceso de conteo. En este artículo se ... -
Fundamentals of silicene
(2017-08-02)Silicene is a single atomic layer of silicon (Si) much like graphene, the first example of an elemental twodimensional (2D) nanomaterial whose study led to the 2010 Nobel Prize in Physics. Until 2010 or so, the only known ... -
Fundamentos de Química Orgánica
(1985)Este libro es una introducción a la Química Orgánica, para estudiantes de carreras médicas, Microbiología, Biología, Agricultura, Veterinaria. Llena un vacío entre textos escolares y libros de texto de la carrera de Química. -
Fungal and Bacterial Co-Bioaugmentation of a Pesticide-Degrading Biomixture: Pesticide Removal and Community Structure Variations during Different Treatments | SpringerLink
(Springer, 2021)Biopurification systems (BPS) are employed for the treatment of pesticide-containing wastewaters. In this work, a biomixture (active core of BPS) complemented by the addition of the fungus Trametes versicolor was evaluated ... -
Fungal bioaugmentation of two rice husk-based biomixtures for the removal of carbofuran in on-farm biopurification systems
(2016-02)The ligninolytic fungus Trametes versicolor was employed in the bioaugmentation of compost- (GCS) and peat-based (GTS) biomixtures for the removal of the insecticide-nematicide carbofuran (CFN). Among several lignocellulosic ...
